Hey guys,
I'm swapping out my front lower control arms and need some specs. I need the torque for the ball joint, radius rod and main bolt that holds it to the car - the pivot point.

C'mon Pedders guys, I know you have the answers!

Thanks in advance,
Craig

Quick question for an old thread, how on earth do you guys get a socket on the nut for the ball joint stud, there's just not any room! I tried getting a socket by itself on the nut earlier today and the socket didn't come anywhere close, making having a torque wrench attched to it even more difficult.

My question is, what have you guys done to torque down that nut to the required 44 lb/ft? I'm looking to do my control arm bushings this weekend and would like to have the control arm removed for this circus.

What I do sometimes is to find another nut with a higher torque spec
then torque it to the desired torque spec (in this case 44 ft/lb) with a
torque wrench. Then put an open-ended wrench onto that nut and
tighten it until it moves a tad. Then immediately go over and torque
the problematic nut, "remembering" what the desired torque feels like.

It's all a bit lame.

For the nut on the control arm ball joint you might be able to get
a torque wrench onto it with an extension and a crows-foot.

44 ft/lbs isn't all that much - you can get a lot more than that with
an ordinary wrench. So don't go crazy and over-torque it.
